If you haven't heard of Eric Daman, you may not be among the most fashion-saavy of the world. However, if you haven't heard of Gossip Girl, you've been living under a rock. Eric Daman is the costume designer for the popular series, and recent designer for the Henri Bendi windows on 5th Avenue. Last night, YSL Beate & Henri Bendel hosted a celebration in honor of the designer and the show and hundreds of young fans came to see the Gossip Girls walk the red carpet with their designer in tow.

Leighton Meester really looked STUNNING last night, as well as the rest of the girls, though isn't Taylor Momsen dressed a little out of her age group? I guess she's sick of playing the innocent bystander. It also looks like the violent trend that is set to sweep fall, is in full effect. I'm loving it.
